Final answer:
It will take approximately 10.1 years for the balance of the account to reach $9500.
Step-by-step explanation:
To find the number of years it will take for the balance of the account to be $9500, we can use the formula for simple interest. We know that Hailey opened the account with $6000 and the account earns 5.75% simple annual interest. Let's represent the number of years as 'n'.
The formula for simple interest is: Interest = Principal x Rate x Time
Plugging in the given values, we have: (9500 - 6000) = (6000 x 0.0575 x n)
Simplifying the equation, we get: 3500 = 345n
Dividing both sides by 345, we get: n = 10.14
Rounding to the nearest tenth, it will take approximately 10.1 years for the balance of the account to reach $9500.
